Electrical Requirements
The minimum feeder size is determined by the current rating (ampacity) of the circuit protection
device listed below. In some cases a larger size may be necessary in accordance with local
regulations for total source.
A 6AWG1/0 (55 sq. mm) ground wire is recommended in all cases.
